EDVARD VOCKLER, OF WHEELING, WEST VIRGINIA.

AGITATOR- FOR LllVllNG-VATS.

SPECIFICATION forming' part of Letters Pai-.entY No. 637,685, dated November 21, 1899.

Application led June 13, 1899 Serial No. 720,423. (No modell) To all whom it iwal/concern.-

Be it known that I, EDWARD VOCKLER, a citizen of the United States,residin g at Wheeling, county of Ohio, State of West Virginia, have invented certain new and useful Improvements in Liming and Bating Vats, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure 1 is a longitudinal vertical sectional View of a tan-vat provided with my improved devices; Fig. 2, a horizontal sectional view on the line 2 of Fig. l, and Fig. 3 a transverse sectional view on line 3X of Fig. l.

vThe object of this invention is to provide apparatus for violently agitating the liming liquor to prevent the lime settling and to keep it evenly distributed through the liquor, so that the hides will be affected uniformly over all their surfaces while in the vat, said apparatus being adapted to be folded and entirely and bodily removed from the vat to facilitate the cleaning of the interior thereof. The apparatus is equally well adapted forbating hides.

Referring to the various parts by numerals, l designates the vat, near the open top of which a horizontal rectangular rocking frame 2 is mounted on horizontal trunnions 3, projecting outward from the center of the longitudinal bars of said frame. Hinged at their upper ends to the center of the end bars of this frame and depending therefrom are links 4, which are pivotally connected at their lower ends to transverse bars 6. Hinged to each of these bars 6, at the inner edge thereof, is a set of paddles or agitator-bars 7, which extend inward from said bars 6 and bear pivotally on a transverse bar 8. The inner parts of the paddles of each set extend past the correspondin g parts of the paddles of the other set, as shown, the paddles of one set lying between those of the other set and extending practically to the pivotal points or support 8 of the other set. y To maintain these paddles in position on the pivot-bars, recesses are cut in said bars,.in which the paddles tit, and fastened over the paddles supported by each bar is a retainer-bar 9, which at one end fits in a socket 10 and at its other end is removably held in position by means of a staple 11, slotted plate 12, carried by the bar, and the removable pin 13. The pivot-bars 8 lit at these ends'between vertical guides 14, by means of which and the retainer-bars 9 they are removably held in position, and said bars 8 are arched on their under side to permit of a free circulation of the liquid thereunder.

Pivotally connected to one end ofthe frame 2 is a pitman 15, and to this pitman is connected alever 16, by means of which the frame may be rocked. The vertical rocking of the frame on trunnions 3 will rock the paddles on the fulcrum-bars, their inner free ends working up and down in opposite directions and thereby causing a violent agitation of the liming and bating liquors. By reason of the overlapping or interlacing of the paddles, so as tobring the ends of those of one set near to the pivotal points of those of the other set, there will be no point in the tank where the lime will be permitted to settle. This is im'- portant, because if there is no agitation of the liquor under the pivots or at any other pointin the vat lime will accumulate on the bottom at that point.

Secured to the inner side of each end bar of the rocking frame 2 is a bar 17, provided with notches 18, which receive the ends of the hide-supportin g bars 19. These bars are held in position by removable cross-bars 20, which at one of their ends fit in sockets 2l, carried by the side bars of the frame, their other ends being secured in sockets 22, carried by the other side bar by tu rn-buttons 23. The trunnions 3 of the rocking frame are removably held in sockets 24a, carried by the Vat by blocks 24, removably y secured to the inner sides of the vat by suitable removable pins.

When it is desired to clean the vat, the

hide-supporting bars are removed and the retaining-bars 9 taken out. The paddle may then by reason of the hinge connections between the paddles and bars 6 and between links 4 and bars 17 be readily swung up to one side out of the vat. The bars 8 may then be removed, leaving the bottom perfectlyfree to be cleaned. If desired, the blocks 24 may be removed to release pivots 3 and the entire frame 2 be removed from the vat.

A series of perforated pipes 29 may be placed in the bottom of the vat and connected at one end to supply-pipes 27 and 28 for the purpose of aerating the liquor.

TOO

frame supported therein, two sets of'pivoted .Y ragitator-paddles supported in the receptacle, one set being near'each end of the receptacle,

I claim*- .X 1. The combi'n ation oiga vat,a 1rocking the paddles thereof extending inward beyond; the center of jthereoeptacle and terminating near'the pivots of kthe paddles of the. other.y

set, the 4paddles of the two sets linterlacingbe"- tween the pivots of the two sets, and a link connecting eachset to the adjacent endof the rocking frame'. f ,Y

2. The combination lof a vat,` av rocking` frame supported therein, alink hinged to'and depending fromfeach end bar of the rocking frame, vertically-movin g cross-bars pivotally hun'gtor the lower endv of said links, paddles` f hinged to each yof said bars and extending in-l ward? therefrom, a fulcrum-bar for each set of paddles, a retaining-device for 'each'set of paddles, the paddles of the two' sets interlace ingbetween the two fulcrum-bars.V

f 3.' The combination of a vat, twohoriz'ontaL` 'sets of agitator-paddles therein, one' set being pivotally supported at each side of Vthe lcenterof the vat, the paddles thereof extend.v ing .in-ward and being pivotally supported about midway their ends, the paddles of each the'free endsof the paddles of th'e otherset and means for rocking said paddles on their pivotal point. j Y

v4:. Thecombination of a vat, means for supporting the .hides therein, two sets of agtating- VVpaddles pivotallyV supported near the bottom' ofthe vat upon' Vtransversefule'rums, the fnlcrum of each set being at a pointbetween the 1 ends of -the paddles and the adjacent-ends of the paddles'being free to vibrate vertically in opposite directions, and means for rocking the paddles on their fulcrums; simultaneously in opposite directions whereby accumulations of` lime will be avoided. Y

5. The combinationvof the vat, means for supporting thehidesthereim-two sets'of longitudinaly agitating-paddles, each set being *pivotally supported transversely, the inner free portions*` off the 'paddles overlappi'nlg'and alternating, and. means wherebyv the paddles are vibrated vertically in opposite directions simultaneously. e
